That's a $22 backup camera.

I haven't seen it yet, but I don't know why somebody couldn't develop a similar kit to put on the front bumper that could warn about traffic ahead, lane drifting, etc.

A <$100 kit that can retrofit my old beater with some modern features would be money very well spent to protect a multi-thousand dollar asset, personal injury, and liability.

I believe that all manufacturers are required to build in backup cameras now. Why not require all registered vehicles to be retrofitted?

Next up, auto-braking.
